The works in the DIA collection examine the relationship between site-specific installations and natural forces. The concept of the frame, which is used in the logotype, builds a story that land art exists both inside and outside the frame of the gallery space. The squares inside the frame represent sites. With the movement of the frame, the objects it contained are always changing and decentering. Rocks, as a visual stand-in for the tactile materials and elements in land art, penetrate the identity system. What is more, a drawing system was created to introduce several concepts from land art, such as opposing forces, gravity, limitations, etc.
